Why are Colombia's oil and gas reserves declining so rapidly?

The decline is driven by a lack of new exploratory drilling to replace producing reserves, a situation worsened by President Petro's policy of banning new exploration contracts. Without new discoveries, Colombia's existing, mature fields are naturally depleting without being replenished.

How does this situation affect Colombia's state-owned oil company, Ecopetrol?

Ecopetrol is caught in a difficult position, forced to fund the government's green transition initiatives while its core, highly profitable oil and gas business suffers from underinvestment. This dual mandate threatens its financial health and its ability to maintain domestic energy security.

Will Colombia have to import natural gas in the near future?

Yes, Colombia is already importing some gas through its SPEC LNG terminal in Cartagena, and the rapid depletion of onshore reserves means the country will become increasingly dependent on expensive international LNG imports to prevent widespread power outages.

Colombia's Oil and Gas Reserves Keep Shrinking

Analysis

AI-assisted analysis · reviewed by Yuri Kan

Colombia's hydrocarbon sector is facing a severe crisis as proven oil and gas reserves continue their decade-long decline, exacerbated by the anti-fossil fuel policies of President Gustavo Petro's administration. The suspension of new exploration contracts has severely curtailed upstream investment, threatening the country's fiscal stability and energy self-sufficiency. This decline forces the South American nation to confront the imminent prospect of becoming a net energy importer, disrupting its macroeconomic framework.

Key Facts

Colombia's proven crude oil reserves have experienced a continuous decline over the last decade, severely threatening the nation's export revenues.
President Gustavo Petro, Colombia's first leftist leader, has actively deterred fossil fuel investment by halting the award of new hydrocarbon exploration contracts.
The combination of regulatory uncertainty, heightened geopolitical risks, and fiscal reforms has driven major international operators to reduce their capital expenditure in the country.
State-run energy company Ecopetrol is facing immense pressure to balance its traditional oil operations with the government's mandated transition toward renewable energy.
The rapid depletion of natural gas reserves has accelerated timelines for when Colombia will need to rely heavily on expensive liquefied natural gas (LNG) imports to meet domestic demand.

Background & Context

For decades, oil has been Colombia's primary export and a cornerstone of its macroeconomic stability, accounting for a significant portion of foreign direct investment and government revenue. However, the country's geology yields mostly mature, declining fields, requiring constant exploration and enhanced oil recovery techniques to maintain production levels. The election of Gustavo Petro in 2022 marked a radical shift in energy policy, as his administration prioritized global climate commitments over domestic hydrocarbon extraction, effectively freezing the licensing pipeline.

Market Impact

The shrinking reserve base will severely erode Colombia's credit rating and weaken the Colombian peso as oil export revenues dwindle. International oil companies (IOCs) are likely to reallocate their capital to more friendly jurisdictions in the region, such as Guyana and Brazil, leaving Colombia's state-owned Ecopetrol to shoulder the financial burden of declining assets. Furthermore, the transition from an energy exporter to an importer will drive up domestic utility costs, stoking inflation and public discontent.

What to Watch

Industry analysts will closely monitor Ecopetrol's upcoming capital allocation strategies and whether the government will be forced to soften its stance on exploration permits to avert an energy security crisis. Key milestones to watch include the potential renegotiation of existing technical evaluation contracts and the progress of offshore gas exploration in the Caribbean, which represents Colombia's best hope for reversing the reserve decline.
